Edexcel IAL Chemistry A2 19.5 reducing aromatic nitro compounds to amines
For nitrobenzene or nitrobenzoic acids, use tin with concentrated HCl first; NaOH work-up may follow but is not part of the reduction reagent pair.
How this is tested
- State Sn or Fe with concentrated HCl for reducing aromatic nitro compounds.
- Identify the conversion of nitrobenzene to phenylamine as reduction or redox.
- Avoid mixing NaOH into the initial Sn/HCl reduction step when choosing reagents.
